Dear FreeSurfers - There's a new script in the development version called dmri_bids_config. You can get it here: https://raw.githubusercontent.com/freesurfer/freesurfer/dev/scripts/dmri_bid...

There is documentation here: https://surfer.nmr.mgh.harvard.edu/fswiki/dmri_bids_config

It will parse the BIDS directory structure, find all the DWI scans (and field maps, if any), and generate the TRACULA configuration file for you. With this file, you can then run TRACULA to pre-process the DWIs and reconstruct tracts of interest.

As an added bonus, it will also generate an FSGD file, based on the participants.tsv file in your input BIDS directory. The FSGD file can be used for stats with mri_glmfit.

It'd be great to have people test this script on their BIDS datasets and report any issues. Both legacy and newer data welcome!

Thanks, Anastasia.
